The legend tells us of a handsome young man, dressed smartly all in white.

During the period of the Festas Juninas (Saints days in the month of June that in Brazil are celebrated with dancing, traditional foods and lots of fireworks), the man seduces unescorted young women, convincing them to swim in the river with him.

The next day, this mysterious man transforms back into his real shape, a pink dolphin, and is gone.
